Unable to import KFX format ebooks using the DeDRM plugin #492

Open CJShahmeran opened 6 years ago

CJShahmeran commented 6 years ago

I am not able to import Amazon KFX format ebooks into calibre using the DeDRM plugin. The ebooks were all purchased directly from Amazon. Per the plugin readme file, I installed an earlier version of Kindle for PC to prevent downloads of the new format. Calibre still recognizes the KFX format.

If you reverted to an older version of Kindle for PC then you need to delete any books that were downloaded using the newer version and re-download them. That will allow you to avoid KFX.

If you want to import a KFX book anyway then you also need to install the optional KFX Input plugin for calibre. Calibre does not support KFX unless that plugin is installed.

When I uninstalled the current version of KIndle for PC and installed the older version, my books were deleted. I had to go to the Amazon website and re-download each of them. I'm just getting started with ebooks, so only have a few so far. I changed Kindle app versions before installing calibre and the plugin, so there was nothing to clean up in calibre.

Which calibre plugin are you referring to? The only one I installed was the DeDRM tool. Is there another?

People have reported that unchecking the auto-update in Kindle for PC doesn't always stick at first. The book in this log is a KFX file. If you want to decrypt that, the other plugin you need is the KFX Input plugin.

@CJShahmeran Here's the relevant log message:

DeDRM v6.6.0: Failed to decrypt with error: The .kfx DRMION file cannot be decrypted by itself. A .kfx-zip archive containing a DRM voucher is required.

You are attempting to import a KFX file.

Currently, the DeDRM plugin only supports zip archives (so-called ".kfx-zip" files) containing both the KFX .azw and the voucher file. I don't recall how those are supposed to be generated. I think the KFX Input plugin does it.

The KFX input plugin is separate, link here.
